SHIPPING CASE.

Application filed January 9, 1924. Serial No. 685,097.

This invention relates to a shipping case constructed of fibre board or equivalent material. It is the custom now for the trade to use'either a slotted end container or else a recessed end container. However,

there has recently been introduced the flushend three-blank container such as shown in my Patents No. 1,452,588 and No. 1,375,127.

These containers, known as the Bliss Nos. 2

andr, are making rapid strides in supplanting the slottedend container and the recessed end container for the reason that they are more economical containers in the way of Amaterial required to make them and are i5 much stronger and more desirable than the recessed end container.

However, a container of this three-blank type, in Order to get the best results in labor economy in setting it up, requires the use of 'l0 an expensive stitching machine which will simultaneously stitch both the end blanks on each end. Small shippers do not feel warranted in undertaking the expense of the installation of the double-headed stitcher.

lt is the object of the present invention to provide a shipping case which has nearly all the advantages of the Bliss Nos. 2 and 4: boxes, and yet eliminates the necessity of a double head stitcher in setting up and sealing the case.

Furthermore, the case is a two-blank case in which the blanks may be sewed together at the mill on a double head stitcher so the shi per has a. complete box all sewed toget er ready to set up. This is a great advantage in handling, in the case of small shippers. i

for-what is sometimes called a to loader,

f but; which involves the same invention.

Figs. 12 and 13 are sections taken on the correspondsection lines of Fig. ll.

before sealing.

Fig. 15 is a perspective of the/end loader before sealing.

Figs. 16 and 17 are plan views of the two blanks of the top loader.

Referring to Figs. 1 and 2, it will be seen that two blanks are employed, each comprising three walls so that the two blanks form the necessary six walls of the case. Three of the side walls a, b and c are formed by what I call the major blank. The other side wall d and the two end walls e and f are formed by the other blank, which I term the minor blank. In the recessed end case and in the slotted end container, the tour walls of the mainblank are sewed together in a collapsible tube by what is known as a manufacturers seam. I propose to have my case sewed together in a collapsible tube in the same way but two manufacturers seams are required. These are forined by the two manufacturers seam flaps g and 71 which are preferably on the major blank (so that the tube may be stitched by a. double head stitcher) but which could obviously be on the side of the wall d of the minor blank but if here llocated would re sult in considerable waste of material and would not be stitched by a double head stitcher. The mill can stitch the manufact-urers seam flap It and g to the side wall d as shown in Fig. 5; this will make a collapsible tube having the two end walls e. and f permanently secured thereon and which can be secured in place by the aid of the flaps a1, l, and c1, and a2, b2 and c2.

No difficulty will be found in sewing the first end wall f to the flaps a2, b2 and 02 as shown in Figs. 4 and 5; this can be easily done with any form of straight anvil-that can be inserted in the end Of the box. The end liaps may be secured on the inside or Outside; this is a matter of indifference. It will be noticed, however, that only three Haps have to be stitched in place as compared with four flaps on the recessed end box and Yon the Bliss No. 2 and No. 4 boxes. The reason for this is that the end blank "is already integrally united with one of the side walls.

In Fig. 3, l have indicated how the case nov outside of the end wall e; stitches 5, 6, 7, 8

and 9 are taken with the aid of the blade anvil in the position designated k2. These two positions k and k2 of the blade anvil require only one insertion and withdrawal of the anvil so that they are practically one. The case may then be swung around and with the anvil inserted in the position shown at k1, the stitches 10, 11, 12, 13 and 14 may be taken through the flap a1 and end wall e with the fla a1 either on the yinside or on the outside of t e end wall. This completes the sealing of the case.

When the case is completed, the amount of stitching that has been required by' the shipper is no more than required for the well known slotted end container, yet the saving in material over the slotted end container is relatively greater, depending of course, upon the dimensions of the box; it will approximate somewhere in the neighborhood of 20%. The case in itsfinal form has Hush ends 270 degrees on the outside and 90 degrees Qn the inside with clear corners, thus obviating many objections connected with the recessed end case.

In Figs. 11 to 14 inclusive and 16 and 17 I have shown a top or side loader. Here the -minor blank contains two side Walls fm. and

n at its ends, while the major blank has two slde walls o and p at its end. The end walls q and 1' are with the top loader in the middle of the lninor and major blanks. The flaps o1. q1, p1, o2, g2 and p2 are the securin flaps. The manufacturersv seam flaps s an t are not as long for a box of the same dimensions. However, the box is set up and sealed in practically the same way as is shown in Figs. 11 and 12.

It will be seen that the essence of the invention is a shipping case having flush ends made up of two separate blanks of three walls each that can be made up in the form of a collapsible tube b two manufacturers seam flaps, and which 1s provided then with two foldable integral bottom and top walls that may be secured flush in the ends of the tube by shallow flaps. In order to avoid confusion 1n the claims, I am going to refer to the portions of the -case that are rst stitched together in setting the tube up as the bottom, to the final parts that are stitched together to seal the case as the top.

It will be understood that where the term major and minor blanks is used in the claims that the term major blank refers to that part of the blank which is known as the body blank, or the art forming the sides and the end, or en s and side; while the term minor blank refers to that blank which forms an end or side and the to and bottom. More specically, and referring to a two-blank case of the collapsibletype, the major blank is that blank which forms the three sides of the collapsible case, while the minor blank forms the one side and the cover wings for the top and bottom or the two ends, according to the particular type of case.

What I claim is:

1. A shipping case of libre board, or equivalent material, of a type having two blanks each of three walls secured together to form a collapsible tube with foldable top and bottom walls. comprising a major blank forming three of the side walls, each end of said major blank being provided with an integral manufacturers seam flap and one end of each of the three side walls of said blank provided with integral shallow sealing flaps and a minor blank forming a side wall and the foldable top and bottom walls, the manufacturers seam flaps on the ends of the major blank being secured to the center wall of the minor blank.

2. A shipping case of fibre board, or equivalent material, of a type havin two blanks secured to ether to form a col apsi'ble tube with folda le top and bottom walls, comprising a major blank forming three of the side walls, each end of said major blank being provided with an integral manufacturers seam flap, and one or more of the three side walls of said blank being provided with an integral sealing flap, and a minor blank having a plain Wall for completing the fourth side wall and an integral cover flap for clos- ,ing the top or loading end of the case, two of the side walls of the major blank being positioned against the side wall of the minor blank, and the manufacturers seam flaps on the ends of the major blank being folded within' and parallel to the plane of the side wall of the minor blank whereby/ the manufacturers seam flaps may be simultaneously stitched to form a collapsible tube ready for shipping.

In' testimony whereof I have aiiixed my signature.
